[SCSI] zfcp: Remove some port flags
PORT_PHYS_CLOSING is only set and cleared, but not actually used for status checking. PORT_INVALID_WWPN is set when the GID_PN request does not return a d_id for a remote port, e.g. when a remote port has been unplugged. For this case, the d_id is zero. In the erp we can check the d_id and use the normal escalation procedure that gives up after three retries and remove the special case. PORT_NO_WWPN is unused: Each port in the remote port list has a valid wwpn. The WKA ports are now tracked outside the port list. Remove the PORT_NO_WWPN flag, since this is no longer set for any port.
